Abstract

Способ отключения подводного гидравлического устройства предусматривает предоставление гидравлического устройства, которое может эксплуатироваться под водой, причем указанное устройство содержит гидравлический цилиндр со штоком толкателя и поршнем. Устройство опускают ниже поверхности воды с помощью барабана для гидравлических шлангов, находящегося над поверхностью воды, например на морском судне. Барабан для гидравлических шлангов включает первый и второй гидравлические шланги, подключенные к цилиндру с противоположных сторон поршня. Расход жидкости в первом и втором гидравлических шлангах непрерывно контролируют. Компьютером или контроллером непрерывно рассчитывают отношение объема жидкости, втекающей в цилиндр по одну сторону поршня, к объему жидкости, втекающей в цилиндр по другую сторону поршня. Гидравлическое устройство отключают, если указанное отношение отличается от заданного значения. Один вариант осуществления включает несколько расходомеров для измерения потока жидкости в одно или несколько устройств с гидравлическим приводом и из них. Согласно одному варианту осуществления выходные сигналы расходомеров анализируют для определения, имеет ли гидравлическая система утечку, и, если обнаружена утечка, выдают предупреждение, и/или отключают одно или несколько устройств с гидравлическим приводом, и/или отключают источник гидравлической мощности.A method for shutting down the underwater hydraulic device provides for providing a hydraulic device that can be operated underwater, said device comprising a hydraulic cylinder with a pusher rod and a piston. The device is lowered below the surface of the water using a drum for hydraulic hoses located above the surface of the water, for example on a seagoing vessel. The hydraulic hose reel includes first and second hydraulic hoses connected to the cylinder on opposite sides of the piston. The flow rate of the fluid in the first and second hydraulic hoses is continuously monitored. The computer or controller continuously calculates the ratio of the volume of fluid flowing into the cylinder on one side of the piston, to the volume of fluid flowing into the cylinder on the other side of the piston. The hydraulic device is turned off if the specified ratio is different from the set value. One embodiment includes several flow meters for measuring fluid flow to and from one or more hydraulically driven devices. In one embodiment, the output signals of the flow meters are analyzed to determine if the hydraulic system is leaking, and if a leak is detected, a warning is issued, and / or one or more hydraulically driven devices are turned off, and / or the hydraulic power source is turned off.
